86 THE FLORA OF THE NORTHERN TERRITORY. 



The pedicels arise in pairs, and in the specimens here collected some have 

 fused, resulting in the formation of flowers with two carpels on the one pedicel, 

 as shown in Fig. VI. Kgs. VII., VIII., and IX. show transition stages in the 

 fusion of the pedicels. Fig. VII. shows the complete fusion of the glands leaving 

 only one gland. 



The species seems nearest H. chordophylla, F. v. M. ; but differs in the 

 pubescent pedicels and perianths, and in the convex stigmatic disc. The 

 tendency for the fusion of pedicels is probably also a specific characteristic. 



5. H. intermedia, Eivart and Daviea (Plate X.). — 60 miles N.E. of Camp 

 II., G. F. Hill (287a), 7/6/1911. 



37 miles E. of Hermansburg, Finke River, G. F. Hill (No. 108), 21/3/1911. 

 Up to 15 ft. 



Near Jay Gorge, Jay River, G. F. Hill (No. Ill), 21/3/1911. 



15 ft. high. Leaves terete, smooth, trifid or quadrifid. Whole leaf 

 barely 11 cm. long. Racemes cyhndrical, in axils, and in terminal panicles. 

 Racemes 7 to 8 cm. long ; rachis, pedicels, and perianths pubescent, the pedicels 

 and perianths more so than the rachis. Pedicels 5 cm. long. Perianth tube 

 8 to 10 cm. long. Gland prominent, horse-shoe shaped, with lengthened cusps. 

 Torus obUque. Ovary shortly stipitate, glabrous. Stigmatic disc obhque, 

 convex, with small prominent swelling. Fruit described from a second specimen 

 without flowers. Fruit 4-^ by 1^ cm., obliquely ovate-lanceolate, obtuse, with 

 mucronate point. Seed-wing not decurrent, convex over nucleus. The species 

 most resembles H. lorea, R. Br. ; it differs in the size and shape of the leaf, and 

 in the shape of the stigmatic disc, as that of H. lorea does not end in a prominent 

 httle swelling hke H. intermedia. This difference is easily seen by comparing 

 Figs. IV. and V. 



H. intermedia also closely resemble H. Ednieana, in general appearance, 

 but the leaves and the whole plant of H. Ednieana are much smaller. The 

 whole leaf of H. Ednieana measures about 3 cm., that of H. intermedia 11 cm. 

 The stigrnatic discs are also quite different, that of H. Ednieana being somewhat 

 sharply pointed (Fig. VI.). On the whole H. intermedia seems to be an inter- 

 mediate species between H. Ednieana and H. lorea.
